I just recently got my Macbook Pro (from maybe 2 years ago, prior to the unibody fits and even before Leopard) back from the Apple store to fix the Hard Drive. I got a general question though: Does Apple replace or repair hard drives? This one was changed from the Tiger I sent it in with to Leopard , but I'm just wondering if they actually repair over replace or vice versa for Hard drives. Or does it depend on the notebook? I think the battery was replaced too as some extra background info (not really relevant though lol) so I'm thinking the drive and battery are new all together? EDIT: By the way, the issue was more than likely a physical crash, as it would keep clicking before we got it fixed. It all leads me to think that, as noted in the replies (thanks), the hard drive is a new one, since fixing one with a physical issue would be unreasonably difficult.
